Abstract

A watertight handhole for the transit of cables in outdoor areas comprised of two cubic or other shaped units, one external and one internal, bonded together (monoblock), made of polyvinyl, cast iron, steel or stainless steel. The handhole of the present invention has one more unit than the known handholes in current use. Its external unit does not have a bottom floor and its sides are (partially) perforated for the removal of any water that may enter, protecting in this way the internal unit which houses the cables and the top of which closes with a flat plate that extends slightly beyond its main body. The bottom floor of the internal unit is conical and ends with a hole which is closed by a conical plug. Both the hole and the plug are threaded. The conical plug has a slot which allows it to be easily opened for the removal of water in the event the unit requires cleaning. The absence of flexible gaskets or metallic screws between the main bodies and plates of the units reduces the total cost of the handhole.
